Sonic Mania Stage Bins: An initial look at the background data

Offzip is great for finding and decompressing the DEFLATEd blocks!
Make sure to use it with a low -m value to make sure you catch the smaller ones! A lot of them are less than the default minimum of 32.

Block 1 per background set:
Not quite sure what these are just yet? I think it's some sort of grouping, or maybe rules of some kind. Needs looking into.

Block 2 per background set:
These are two bytes per tile.
The first byte is the tile ID.
The second byte is probably either rules or a scroll velocity. The first four bits of this value can be changed, but you'll have to decompress and check the hex for the other values.
